:eek: Help, I just bought two teacup chihuahuas. They are brother and sister. One is lively, and plays all day. The other obviously calm (personality) but like overnight, puppy starts moaning for no reason, is stubborn about eating, no vomiting, no diarrhea yet (seldom eats) sleeps the entire day. I had them for a week already, and the one that acts if he is sick looks skinnier really quick and is wobbly from the back legs and can't tilt his head without falling. We spent all our money on buying them and we were told they had their first set of shots already. Oh, and they are 10 weeks old.:confused: He is constantly moaning and it is a helpless feeling.
